High Torque Ball Mill Synchronous Motor

High torque ball mill synchronous motor boasts a rated torque multiplier of ≥2.0, exceeding the industry's conventional motors (1.6-1.8 times).
Its optimized rotor structure, high-performance materials, and excitation system ensure continuous high torque output, with a torque density of ≥80 N·m/kg.
This represents a 20%-25% increase in torque at the same power level.
It can effectively handle full dynamic loads while maintaining stable speed.
This ensures stable production capacity: even sudden changes in ore hardness, the motor will not experience a drop in grinding efficiency due to insufficient torque. Based on an average 12-hour daily full-load operation, this can avoid approximately 20-30 tons of production capacity loss per month.

Furthermore, equipment investment costs are reduced: the purchase, installation, and maintenance costs of a torque amplification device are eliminated. For example, the initial investment per unit can be reduced by 15%-20%, resulting in annual maintenance costs savings of 8,000-12,000 yuan.

Furthermore, the high-torque design extends equipment life: low-load operation reduces motor winding temperature by 5-8°C and bearing wear by 30%, extending the motor's estimated service life from 15 years to... 18-20 years, matching the long-term operational needs of the mine.

High torque ball mill synchronous motor produced by Milestone Motor is equipped with an RS-485 communication interface, supports industrial communication protocols such as Modbus-RTU, and has 12 built-in operating parameter monitoring sensors, including stator temperature (3 channels), bearing temperature (2 channels each at the front and rear ends), motor vibration (1 channel each for horizontal/vertical/axial), excitation current/voltage, speed, etc.; it supports remote start and stop, parameter setting and fault warning functions, and the warning threshold can be customized through the PLC system, realizing real-time data exchange between "equipment-control system-operation and maintenance personnel" to accurately capture abnormal signals (such as sudden rise in bearing temperature and vibration value exceeding the limit), avoiding fault omission caused by single parameter monitoring, which greatly reduces labor costs and reduces downtime losses. Maintenance personnel can shorten the average fault handling time from 4 hours to 1 hour through early warning and precise fault location.

After our large-scale copper mining customer in Africa adopted Milestone's 3000kw high torque ball mill synchronous motor, the intelligent linkage system reduced the number of motor failure shutdowns from 8 times per year to 2 times, reducing annual downtime losses by approximately US$130,000. Milestone Motor has been deeply engaged in the research and development and manufacturing of high-torque synchronous motors for more than 20 years, providing customers with high-quality services and products.
